摘要：
In this article, a local discontinuous Galerkin (LDG) method is studied for numerically solving the fractal mobile/immobile transport equation with a new time Caputo-Fabrizio fractional derivative. The stability of the LDG scheme is proven, and a priori error estimates with the second-order temporal convergence rate and the (k + 1)th order spatial convergence rate are derived in detail. Finally, numerical experiments based on P-k, k = 0, 1, 2, 3, elements are provided to verify our theoretical results.
